The book "Wild Fermentation: The Flavor, Nutrition, and Craft of Live-Culture Foods" by Sandor Ellix Katz was my introduction to trying my hand at homemade soft drinks. I have successfully made yogurt and am making my own Kefir - so why not try this? The book explains that Ginger Beer is a Caribbean-style soft drink that begins with the "ginger bug" to start the fermenation process. The bug offers just enough fermentation to create carbonation but not enough to create a significant amount of alcohol.
So what is the ginger bug? Simply water, sugar, and grated ginger. This easy starter can be used as yeast in any alcohol ferment or to start sourdough. The recipe suggests 2-3 weeks for the beer to be ready, but mine took less time. My house is quite warm, I suspect that might have something to do with it.
Ingredients (for 1 gallon or 4 liters):
3 inches/8cm or more fresh gingerroot
2 cups/500 ml sugar (I used organic cane juice crystals)
2 lemons (I love cooking with lime, so I used lime instead)
Water (I used water purified with my Get Clean Water Pitcher*, if I were the ginger bug I would not appreciate impurities in the water)
Process:
1. Start the "ginger bug" : Add 2 teaspoons (10 ml) grated ginger including skin and 2 teaspoons (10 ml) sugar to 1 cup (250 ml) water. Stir well and leave in a warm spot, covered with cheesecloth to allow free circulation of air while keeping everything else out. I had cheese cloth, but you could also use CLEAN tights or nylons (just a suggestion since I am a master for repurposing). Add this amount of ginger and sugar everyday or two and stir, until the bug starts bubbling. This will take anywhere from 2 days to 1 week.
2. Make the ginger beer any time after the bug becomes active. If you wait more than a couple of days, keep feeding the bug fresh ginger and sugar every 2 days. Boil 2 quarts (2 liters) of water. Add about 2 inches (5 cm) of grated gingerroot (the more gingerroot you add, up to 6 inches/15 cm the more intense the ginger flavor) and 1 1/2 cups (375 ml) sugar. Boil this mixture for about 15 minutes. Cool.
3. Once the ginger-sugar-water mixture has cooled, strain the ginger out and add the juice of 2 lemons/limes and the strained ginger bug. If you intend to continue making ginger beer, reserve a few tablespoons of the active bug as a starter. Replenish it with additional water, grated ginger, and sugar.Back to the ginger beer - add enough water to make 1 gallon (4 liters).
4. Bottle in sealable bottles. Some examples are empty soda bottles with screw tops, rubber gasket "bail-top" bottles, sealable juice jugs, or canning jars. Leave bottles to ferment in a warm spot for about two weeks. Mine was about ready in one week.
5. Cool before opening. Remember to be prepared with a glass since carbonation can be strong.
My 4 year old enjoyed this with a ratio of 10% Ginger Beer to 90% Water. We do not drink soda, so he was not used to the "spice" or carbonation.
So try this out and let me know what you think!
